12. Knowledge Sources / B. Perception / 5. Interpretation
Kant showed that our perceptions are partly constructed from our concepts
     Full Idea: It was Kant's great discovery that the object of knowledge is not simply given but constructed, and that it contains conceptual elements not contained in pure perception.
     From: Hans Reichenbach (The Theory of Relativity and A Priori Knowledge [1965], p.49), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap
26. Natural Theory / C. Causation / 5. Direction of causation
A theory of causal relations yields an asymmetry which defines the direction of time
     Full Idea: Reichenbach wanted to implement a causal theory of time. He did not stipulate that causes are temporally prior to their effects. Instead, he constructs a theory of causal relations to yield a causal asymmetry which is used to define temporal priority.
     From: report of Hans Reichenbach (The Direction of Time [1956]) by Wesley Salmon - Probabilistic Causality
     A reaction: I find his approach implausible. I suspect strong empiricism is behind it - that he wants to build from observable causes to unobservable time, not vice versa. But normal intuition sees time as one of the bedrocks of reality, making events possible.
27. Natural Reality / C. Space-Time / 2. Time / a. Time
The direction of time is grounded in the direction of causation
     Full Idea: Reichenbach argued that temporal asymmetry is grounded in causal asymmetry.
     From: report of Hans Reichenbach (The Direction of Time [1956]) by J Ladyman / D Ross - Every Thing Must Go
     A reaction: I'm not sure that I can make sense of giving priority either to time or to causation when it comes to this asymmetry. How do you decide which one is boss?
